| 摘 要： | 对缺氧─好氧工艺处理印染废水可行性进行了试验研究，取得了工程设计所需的试验数据．研究表明：当进水ＣＯＤ＝１８００ｍｇ／Ｌ，ｐＨ＝１０．０～１０．８，水力停留时间ＨＲＴ＝１３ｈ，则系统出水ＣＯＤ＝２７０ｍｇ／Ｌ，ＣＯＤ平均去除率为８５％．其中二级缺氧段在水力停留时间仅为３．８５ｈ的情况下，使废水ＢＯＤ５／ＣＯＤ由进水０．２左右提高到０．４６～０．４８，ｐＨ值由１０．０～１０．８下降至７．６～８．３，为后续好氧处理创造了有利条件，这是本试验流程能够有效地处理该印染废水的关键．

| Abstract: | in this experiment, the bio-degradability or hard-biodegradable textUe waserwater by partial anaerobic and aerobic processes was studied. Experimental data for reference were obtained for the engineering application design. The experiment showed that if theinfluent COD=1800mg/L(average),pH=10.0-10.8 and the hydraulic retention time HRT=13h then the effluent COD=210mg/L (average) and the COD removal efficiency was 85%.Of the experimental processes, the two partial anaerobic stages changed BOD5/COD of thewastewater from about 0.2 of the in fluent to 0.46-0.48 and pH valume from 10.0-10.8 to7.6-8.3, thus providing suitable conditions for the following aerobic treatment. |
